Oh, apparently I learned something I didn’t know, I assumed monochrome was simply single color. I What is the difference between monochrome and converted? Effective difference as I somewhat understand the phosphor converted. I expect it is the spike in wavelength in the blue freq…
On a separate note, with it being phosphor converted will a RTL collar work with these?
Good point. Their spectral plot shows it peaking just below 525nm and the top of the curve spreading between 525 and 550,but they don’t bin them. In fact the only “bin” they list is “A” and they only associate that against brightness bin 5P
how is the beam in the 2mm^2 version? I see the die is rectangular, I wanted to use it in a C8 host but I don’t know if the beam is going to be right or this led should be used only with aspherical lens
the sofirn c8t driver can be bought from sofirn store on ali. its max 4.5 amp according to them.
Is there a reason this wouldnt work?
its pwm tho so regulated should be better right?
Osram on left, stock on right.
In real stock is more warm than on the picture and Osram is less blue.
T:2s ISO 200 F: 4
I didn’t measured throw.
Yesterday was foggy.
From 5m osram has a hole inside the beam.
I guess the correct distance to measure is around 25 m.
You are right! :+1:
I measured osram led lights and GT xhp35HI version at 15, 20, 25m
If you have a hole in the beam at 5, 10m in MF04 with osram you are close to good focus. From the image I think it is perfectly dialed in.
The distance in which the hole dissappears depends on the relation of the diameter of the reflector to the size of the LED. The bigger it is, the longer the distance.
I documented my experiences regarding this topic here and did some simulations here and here (in German).
All focused lights should have a hole in their beam at close range. Even small edc type lights will have a donut-hole hotspot in the first couple of inches of their beam. Super throwers will have this hole for many meters.
I wish someone would make a new thread solely about focusing thrower LEDs with steps, tips and best practices. It’s one of those things people talk about but never in detail. When I made a thread about how crappy my spring bypasses were everyone chimed in and I think it was very helpful basic topic (to me) to rehash after so long.
